2. Grand Theft Auto 5 Release Date, Wii U Port
The game exists. It's in development. But Rockstar Games has said next to nothing about it since its announcement late last year. The reason for that is because Rockstar doesn't want any talk of Grand Theft Auto 5 to cannibalize the company's current marketing drive for their only game this year, Max Payne 3.
Rockstar Games, like Blizzard Entertainment, is a studio with a tradition of releasing only one game a year, and this year isn't likely to be any different.
Furthermore, it's unlikely that the studio will make any commitments to the Nintendo Wii U with Grand Theft Auto 5, especially given that they have yet to do so with Max Payne 3. It'd be more likely that they would announce their existing games like Red Dead Redemption and L.A. Noire for the Wii U before committing to it with a game with no release date.
